Removable EMI cover for a media drive housing

Abstract

An EMI cover for a media drive housing. The cover includes a conductive surface adapted to cover one end of the housing. Conductive flanges are disposed along the sides of the surface. A first flange hingingly engages the housing. A second flange catchingly engages the housing. Attachment and removal of the cover may be achieved without the use of fasteners or tools. Protrusions disposed along the periphery of the cover enhance EMI blocking characteristics of the cover. A raised section of one of the flanges may extend over a portion of the housing to form an EMI-efficient cable management port.
